EYEGLASSES AND SPECTACLES.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed July 14, 1910. Serial No. 571,942.

To all who m, it may concern Be it known that I, NELSON M. BAKER, a citizen of the United States, residing at Southbridge, in the county of WVor-cester and State of Massachusetts, have invented certain new and useful Improvements in Eyeglasses and Spectacles, of which the following is a specification.

My invention relates to the construction of bearing pads as commonly attached to the nose engaging portion of eyeglasses and spectacles.

Previous to my invention it has been the practice to attach a bearing pad to the nose clip by means of a pin or shank extending entirely through the pad leaving the head of the pin or shank exposed onthe side next to the wearers nose. Incases where the pin was constructed of a precious metal,

having a base metal core, the head of the pin would leave exposed a portion of base metal. Perspiration would act on and corrode this base metal to such an extent that objectionable marks would be left on the wearers nose. Hence, to avoid this objection it was necessary to use a pin composed entirely of an expensive noncorrosive metal, usually of gold.

One object of my invention is to produce an inexpensive bearing pad having a noncorrosive bearing surface which will permit of the use of the usual attaching pin having a base metal core. I

Another object of my invention is to provide a structure which will be attachable either as a rigid or a rocking pad, in order that both of these forms of pads may be made with the one set of tools, the desired form being obtained by merely altering the size of the opening for the pin, the diameter of the pin or the size of the false back, as the case may be.

Each of the pads illustrated in the drawing has a noncorrosive bearing face and a false back carrying the pin used to connect the pad and the nose engaging arm of the eyeglass or spectacle, said false back being either integral with or separate from the 1n. p Figures 1 and 2 of the drawing are views showing the plan and sectional elevation of a nose guard for eyeglasses provided with my improved pad. The diameter of the pin is made smaller than the opening in the nose clip, allowing the pad to rotatevand to move laterally whereby it may adjust itself to the nose. Figs. 3 and 41 show the plan and sectional elevation of a pad rigidly attached to the nose clip, the outer face being rigidly secured to the false back plate. Figs. 5 and 6 show the plan and sectional elevation of a modification of the form of pad shown in Figs. 3 and 4. Figs. 7 and 8 show the plan and sectional elevation of a pad wherein the false back is rigidly attached to the nose clip, but the diameter of the false back is less than that of the outer face thereby allowing rotary and lateral movements of the outer face relative to the false back. Figs. 9 and 10 show the plan and sectional elevation of a pad wherein the false back is rigidly attached to the outer face and the connecting pin is rigidly attached to the nose clip, but the diameter of the pin is smaller than the opening in the false back, thereby permitting of rotary and lateral movements of the pad relative to the nose clip. Figs. 11, 12 and 13 show the plan and sectional elevation and pad blank of a pad wherein extension arms on the sides of the outer face are bent backwardly and centrally to form the false back and the pin is rigidly connected to the nose clip, but the opening in the extension arms forming the back is larger than the diameter of the pin, thereby permitting rotary and lateral movements of the pad relative to the nose clip.

The pads consist of a noncorrosive outer face 1 which is shaped up by any preferred means to bear on the nose and flanged over or otherwise attached to a false back plate 2. The back plate 2 is attached to the nose clip 3 by a single pin or shank 4 located at the center of the false back 2. The back plate 2 and the pin 3 may be made integral if so desired. There are two forms or classes of these pads. In one class the pad is rigidly secured to the nose clip and there is no movement of the pad relative to the nose clip. In the second class the pad 1s arranged to have both a rotary and lateral or rocking movement relative to the nose clip. This ing the opening in the nose clip of greater diameter than the pin secured to the false back of the pad, by making the false back smaller in diameter than the pad and promovement is obtained by male.

viding peripheral flanges so that the outer face may move on the false back, and by attaching the outer face rigidly to the false back and making the opening in the false back larger in diameter than the securing pin. The rocking of the pad may be facilitated by using a back plate having a rounded or convex surface and by cupping out or countersinking the edges of the nose clip around the opening for the heady of the pin; as the head of the pin is larger than the opening it prevents the pad from slipping off.

The rocking movement relative to the nose clip permits the pads to adjust themselves and lie flat against the side of the nose. here pads rigidly secured to the guards are used, adjustment for the nose is made by bending or twisting the nose clips so that the pad may be brought into desired position.

I am aware that previous to my invention flexible, suction and semiplastic bearing pads of soft rubber and like materials have been applied to the nose bearing arms of spectacles and eyeglasses, but said suction or plastic pads become foul, mar the flesh and have to be replaced at short intervals, and I therefore desire to contrast my improvements therewith and to specifically point out that by the use of a hard, noncorrosive face plate for the bearing surface of my pad, a permanent structure which will not mar the flesh, is obtained. It will also be noted that the method of operation of my pad is unlike that of a suction or plastic pad. The suction or plastic pad. is designed to cling to the nose by means of the plastic nature and elasticity of the material from which it is constructed, whereas a hard, non-flexible pad is held in place entirely by external forces exerted through the nose bearing arm.

Having now described my invention, what I claim as new and desire to secure 'by Letters Patent is:

1. The combination with a nose clip, of a bearing pad having its edge inturned, and means carried by the clip for loosely engaging said inturned portion to secure the pad to the clip.

2. The combination with a bearing pad having an inturned peripheral flange, of a back plate of greater diameter than the diameter of the aperture inclosed by the flange, said back plate being loosely mounted in the cup formed by the inturned flange of the pad, and means for securing the back plate to a nose clip.

3. The combination with a nose clip having a plate secured thereto, of a bearing pad having a reversely bent peripheral flange fitting around the outer portion of the plate to loosely secure the pad to the plate and permit of relative movement of the pad and plate while preventing separation thereof.

l. The combination with a cupped bearing pad having an imperforate nose engaging portion, of a nose clip for supporting the pad having an aperture formed therein, and a rivet engaged in the aperture of the clip, and having an enlarged portion on one end retaining the rivet against disengagement from the clip, and having an enlargement on the other end fitting within the concavity of the pad, the material of the pad being forced inward into engagement with the enlargement of the rivet to secure the pad thereto, the rivet having loose engagement with one of the two first named parts whereby the said parts may automatically adjust themselves relative to each other.

In testimony whereof, I affix my signature in presence of two witnesses.
